The desert sand is very hot during the day and very cold at night. What does this tell you about its specific heat capacity?
erma4kov [3.2K]

Answer: The specific heat capacity is very low.

Explanation:

The specific heat capacity of a body is defined as the heat energy required by a body to cause a unit change in its temperature. The value is over low that is why it is easier for the desert sand to easily get very hot during the day. Conversely, it is very easy for the desert sand to lose it's heat a cool breeze pass over it in the night making it very cold in the night. This value also defines how long the desert sand can retain heat. Therefore, the desert sand has a low specific heat capacity.
